Phone privacy is an increasingly relevant issue. In a 2015 study, the Pew Internet Research Center reported that more than half of all U.S. smartphone owners use their phone for online banking and to look up medical information. A separate survey conducted by MobilePhoneChecker in the UK found that 34 percent of women and 62 percent of men have checked their significant other's phone at least once. Phone snooping at the workplace and among friends has also become worryingly commonplace.

"How can I make sure my phone is totally safe from prying eyes? That's the question on everyone's mind. And we realized that there wasn't a great answer out there," said DU Privacy Vault team leader Pan Jinfeng. "That inspired us to make a complete privacy solution for everyone. You can easily and securely lock your phone from would-be snoopers," he said.

In the name of preserving privacy, DU Privacy Vault showcases the following features:

App Lock: Lock all of your apps with a single gesture-based password. Secure your smartphone and completely protect your privacy.

Lock Cover: Disguise your lock screen as something else. A fake 'App Crash' screen cover and a 'Fingerprint Scan' screen cover are now included. More screen covers will be available for download soon.

Photo/Video Safe Vault: Hide and encrypt your photos and videos with DU Privacy Vault. Never again worry about other people peeking in on your gallery.

Prevent Uninstall: After you turn on the Prevent Uninstall feature, other people won't be able to delete DU Privacy Vault from your phone without your authorization.

Lock Delay: Within the time limit you set, you won't need to unlock your apps again when you reopen them.
